Abstract
A display device with improved color and grey scale capability employs an improved time dependent dithering technique. In the display device, each pixel is controlled so as to be illuminated for only a certain number of times during a display time period, the number of illuminations during the display period being dependent on the color or grey scale value of a corresponding pixel in an original image and a dither matrix element. After each frame in the fixed time period, the dither matrix elements are circulated to a new position, thereby introducing a time factor into the dithering technique.
